Can rain trigger a volcanic eruption

The notion that rain could lead to a volcanic eruption may seem strange, but scientists from the University of Miami in the USA, have used information from satellites, including the Copernicus Sentinel-1 mission, to discover that a period of heavy rainfall may have triggered the four month-long eruption of Hawaii’s Kilauea volcano in 2018.

NASA’s Webb Telescope to Unravel Riddles of a Stellar Nursery

imagea_orion-1969x2000_0.png
This color-composite mosaic of the central part of the Orion Nebula is based on 81 images from the European Southern Observatory (ESO) Very Large Telescope at the Paranal Observatory in Chile. The famous Trapezium stars appear near the center, amid the Trapezium Cluster, the very crowded home of more than a thousand young stars. Researchers will train Webb on this region to study phenomena associated with the birth of stars and planets.
